On Time Mall Inc. began in 1983 as On Time Air Conditioning Inc. a heating and air conditioning service and installation contractor. In 1999 the contracting firm was sold off and we decided to concentrate on providing indoor air quality products to our clients across the world.
Our founder Jay Guliano has been in the industry for over 48 years and is considered a national expert on the indoor air quality field. He has owned and operated 2 different successful heating and air conditioning firms, managed several others, and provided consulting services for industry manufacturers as well as other contractors. He still answers the phone at times and assists clients whenever possible. Originally from Pittsburgh PA he moved to Phoenix in 1979 to get out of the cold with his wife and has been here ever since.
